RISC-V: KVM: Fix KVM_GET_REG_LIST API for ISA_EXT registers
The ISA_EXT registers to enabled/disable ISA extensions for VCPU
are always available when underlying host has the corresponding
ISA extension. The copy_isa_ext_reg_indices() called by the
KVM_GET_REG_LIST API does not align with this expectation so
let's fix it.
